United States Patent 3,158,999 SASH FRAPAE George Alfred Downs, 680 Breys Ave., Salem, Greg. Filed Dec. '12, 1961, Ser. No. 153,750 2 Claims. (Cl. 20-56.1)

This invention relates to new and useful improvements in sash frames and more particularly is concerned with storm window sash frames.

It is an important object of the present invention to provide a sash frame having improved means for removably securing a glass pane therein and also for accommodating glass panes of varying thickness.

It is a more particular object of the present invention to provide a sash frame having a channel portion for the reception of a glass pane, with a portion of the channel for receiving the pane extending angularly inwardly and being yieldable for varying the width of the channel.

It is another object to provide in combination with the channel portion if necessary an improved extruded I filler strip, the latter being utilized with the channel when the pane to be mounted in the channel is thinner than the normal width of the latter.

' Another object is to provide an improved mounting means for a sash frame whereby the latter is readily inserted and removed without the use of fasteners or the like.

' Briefly stated, the sash frame of the present invention in cross section includes a glass pane receiving channel having a first substantially rigid wall and a second yieldable wall ,both leading from a connecting wall. The yieldable Wall is inclined toward the first wall and thus provides an expandable channel opening for accommo dating glass panes of varying thicknesses. A resilient filler strip may be used in combination with the sash frame to serve both as filler means between the yieldable wall and a thin glass pane and to anchor the pane in place. The yieldable wall and fillm strip have novel means for interengagement whereby the latter is anchored on the yieldab-ie wall in a forced connection between the pane and the yieldable wall. The sash frame has means providing for its assemblage and also has means for holding a sealing member.

The invention will be better understood and additional objects thereof will become more apparent from the accompanying specification and claims considered together with the accompanying drawin s, wherein like numerals of reference indicate like parts, and wherein:

FIGURE 1 is a foreshortened sectional view through a window structure showing a sash frame mounted thereon embodying the features of the present invention;

FIGURE 2 is an enlarged cross-sectional view of a filler strip comprising a part of the present invention; and

FIGURE 3 is an enlarged cross-sectional view of the sash frame as used without the filler strip.

Referring now particularly to the drawings and first to FEGURE l, a conventional window structure includes a sill 10, a header 12, a window element 14, and outer window mounting strips 16.

Referring to FIGURE 3 the present invention is con cerned with a pane receiving or sash frame element designated generally by the numeral'2t). Element 20 is preferably an extruded product and in the formation of a rectangular sash frame utilizing the extrusion the prod- 7 3,158,909 Patented Dec. 1, 1964 walls 24 and 26. The wall 24 has a rib 28 extending toward wall 26, and the area between the walls 24 and 26 and between the rib 23 and body 22 forms a socket St for the reception of fasteners, not shown, for securing portions of the sash frarne together at the corners, such being accomplished by inserting such fasteners in the sockets 3G and crimping the ribs 28 thereagainst.

The outer end of wall 26 is reversely angled to form an inwardly opening groove 32., and a rib 34 is provided on body 22 to form with wall 26 a groove 36 co-operating with groove 32 to form a channel which opens on the side of the frame for the reception of a resflient sealing member 38. This sealing member has an angular ton ue 40 which is adapted to en age window structure, or sash frame mounting structure, as Will be apparent hereinafter, to serve a scaling function.

Projecting from the body 22 in a direction opposite from the walls 24, 26 is a first wall 42 which is substantially rigid and a second wall 4-4 which although principally rigid is made yieldable by means of cutout portion 46 along the inner surface thereof and preferably adjacent the juncture of wall 44 with body portion 22. In a preferred construction, the cut-out portion comprises a continuous groove. Wall 42 has a straight inner surface adapted for flush abutment by a sash to be mounted in the frame.

The wall 44 has a projection on its outer end having an inwardly extending rounded portion 48 and an angular extension 59 projecting in the opposite direction. The end of wall 44, formed by rounded portion 48 and extension 50, is inclined, the direction of inclination being such as to lead into the channel formed between the walls 42, 44 so that a pane is readily guided into the channel.

In the formed condition of the element 26, as by extrusion, the wall 4 is angled inwardly toward the Wall 42 as seen in FIGURE 1. The channel by itself is capa'ole of frictionally clamping a glass pane P against the wall 42 provided the pane assumes a thickness greater than the normal dimension between the inner projecting end as and the wall 42-. As apparent in FIGURE 3 a pane l of substantial thickness is mounted in the frame and the wall 4'54 has been bent away from the Wall 42 to accommodate such thick pane.

Referring now particularly to FIGURE 2 a filler strip 5a is utilized in combination with the wall 44 for panes which are thinner than the normal distance between the wall 42 and the projection 48. Filler strip 55 has a body portion 53 and a pair of divergent leg portions 69 and 52 projecting from one side of said body portion. Also, each or" the leg portions projects slightly beyond the opposite side or" the body portion to form a recess 64 therebetween.

To mount a thin pane in the frame, the former is first inserted in the channel portion and then the filler strip 5'6 forced between the pane and the projection 48, the filler strip flattening out as it is pushed into place. Projection 43 on the wall 44 snaps into recess 64 whereby the filler strip is held positively in place to serve as a weather seal and as a friction clamping member for the pane.

For easy mounting and dismonnting of the present storm window sash frame on the window structure it is preferred to employ a pair of channels 66 and 68 secured as by nailing to the upper and lower portions of the window structure, respectively. Each of channels 66, 68 has a pair of walls 79 and'lZ, the Walls 72 being shorter than the walls 719. Furthermore, the sash frame is of less height than the window frame opening and suiiiciently of lesser dimension whereby the frame can first be inserted'upwardly into channel e6 a distance such that its bottom edge clears the top edge of, Wall 72 of the bottom channel 68 and then lowered to rest in the channel 68. The sash frame is thus easily inserted and may be removed simply by a reversal of this procedure. For the purpose of manipulating the frame, itis provided with a handle 74 secured to the bottom element thereof.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the, spirit of'my invention or rior width of said channel members for insertion therein, said pane holding element being formed of a substantiai-ly rigid material and in cross'section having a body portion, a rigid first Wall extending from said body portion at right angles thereto and having a straight pane engaging surface adapted foriflus'h abutment by a pane to be mounted in said element, a second wall ex- {tending from said body portion in the same. general direction as said first wall but inclined inwardly toward said first wall, said second wall forming a pane receiving channel with said first wall and terminating in an enlargement provided with a fiat end edge singularly disposed relative to said second wall for directing a pane into the pane receiving channel, said second wall 'having an outer surface and said enlargement projecting outwardly beyond said outer'surface, means defining a cutout portion in said second wall adjacent its juncture with said body member whereby said wall is yieldable for varying the width of the pane receiving channel adjacent the end of the second wall to engage panes of varying thicknesses, a third wall extending at right angles from said body portion in a direction opposite from said first and second walls and having an outer surface, said third Wall having a groove opening "through its outer surface andbeing disposed normal to the pane receiving channel, a resilient sealing member mounted in the groove in said third Wall having a flexible tongue projecting outwardly into engagement with'one of said inner surfaces of said mounting channel members, and a fourth wall extending from said body portion in parallel spacedrelation to said third well, said fourth wall having an" outer surface engageable with the other inner surface ofsaid mounting channel members,

2. The'sash frame assembly of olainr 1 including a resilient sealing member mounted on said enlargement, said sealing member having divergent leg portions both end-s of which engage a pane in the pane holding element. r
